SPECIFICATION forming part of Lettersatent No. 484,489, dated October 18, 1892.

Application filed January 25, 1891. Serial No. 419,134. (No model.)

To all vwhom t may concern,.- l

Be it known that I, GEORGE E. BLAINE, a citizen of the United States, residing at New Carlisle, in the county o fOlark and State of Ohio, have invented certain new and useful Improvements in Windows, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part 'of this specification.

My invention relates to that class of windows which employ friction-strips for securing the sashes in place and supporting them when raised or lowered to any position desired; and it has for its object the improved construction of such Windows.

The novelty of my invention will be hereinafter set forth, and specifically' pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation of a window embodying my invention and with the front facing and blindstrips removed. Fig. 2 is an enlarged transverse section through the window. Fig. 3 is an enlarged detail broken perspective ot' a portionpf one of the strips and side of the sash. Fig. 4 is an enlarged detail broken perspective of the lower corner of the frame.

The same letters of reference are used to indicate identical parts in all the figures.

A represents any ordinary window-frame, and B the slidingrsashes therefor. In each side of the frame are cut grooves C, extending entirely from the top to the bottom of the frame, as indicated by the dotted lines in Fig. 1. The top and bottom sills are mortised into the sides sufficiently far to nearly, if not entirely, ill the grooves at these points and afford stops for the spring friction-strips D, which t snugly in the` grooves O the entire distance between the top and bottom sills. The dimensions of the strips are such as to just exactly lill the grooves when the former are pressed back, and their outer edges are fluted, as shown, and preferably rounded. The inner or rear edges of the strips are grooved their entire length, as seen at b, to receive the semi-elliptical springs a, preferably of spring-wire of a thickness to snugly fill the width of the grooves l) and having one end bent, as seen at c, and inserted in a perforation in the groove and having the opposite end reversely bent, as at d, and resting on the bottom of the groove. The curved parts of the springs at their middle project from the groove b and bear against the rear walls ot' the grooves C, as shown. There are as many of these springs as the strips will carry without interference with each other, and when the strips D are pressed entirely into the grooves C the springs a are entirely within their grooves b, as will be readily understood. To hold the strips D within the grooves O, I out away their upper and lower projecting edges, as seen in Figs. l and 4, and apply [iat metal strips or plates p, which eX- tend across and cover all the strips and which are secured to the sides ofthe frame by screws e. These plates are mortised flush into the sides of the frame, as shown in Figs. 1 and 4. The outer edges of the sashes on their sides are grooved from top to bottom, as seen at f, Figs. 2 and 3, so as to snugly receive the projecting outer edges of the strips D, and within each of the grooves f, preferably at or near the middle of the sash, is a rubber block g, recessed in the bottom of the groove and rounded on its projecting face to fit one or more of the utes in the strips D, as seen in Fig. 1, without preventing the frictional contact of the remaining parts of the strips with the bottoms of the grooves in the sashes.

It will be seen from the above-described construction that the sashes will be securely held at whatever point they may be raised or lowered, and at the same time will be held from rattling, and the window will be exceedingly air and dust tight when closed. To remove a sash, it is only necessary to press in one of the strips at points above and below the sash, when it can be lifted out. It can be replaced in the same manner.

In Figs. 2 and 4 I have shown additional spring-strips E for sliding blinds or screens, which strips are constructed and applied in the same manner as the strips D, the blinds or screens being grooved, like the sashes.

I am aware that it is not new to employ recessed spring friction-strips engaging grooves in the sashes; but heretofore these strips have been entirely flat on their engagingedges, which prevented their application to windows with heavy sashes.

Having thus fully described my invention, I claim- 1. The combination, with va window sash or blind having longitudinal grooves in its sides, in which are seated rubber blocks, of the Window-frame having spring-strips occupying grooves therein and whose projecting edges are iuted and conlinei in the grooves in the; sash, substantially as described.

2. The combination, with a window sash or 5 blind having longitudinal grooves in itslsidefs, of the friction-strips engaging said grooves and occupying grooves in the sides of the widow-framesandcurved ibow-shaped=springs fa, i occupying grooves in the rearredgesof the ici-ction-strips, said springs having one end bent Ainward and inserted in ,perforations in said last-.named grooves .and hav-ing the'rfopposite ends reversely bent to ride in said grooves, substantially as described. s

3. 1n a sash-supporting device employing spring-strips occupying grooves in the frame and projecting therefrom into grooves in the sashes, the removable retaining-plates p, extending across the tops and bottoms of said strips and secured tto the frames, substantially as and for the purpose specified.

4. The combination, with the side pieces of awindow-frame grooved from end to end to receive spring friction-strips, of the top and bottom pieces mortised into said side pieces l'iioruiing stops for said grooves, lsubstan- 3o tifallly as described.
